Abstract (en)

[origin: EP1074991A2] A semiconductor memory includes a memory (101) having a plurality of input/output terminals (D1 to Dn) for inputting/outputting parallel data; a parallel/serial conversion circuit (202) connected to said parallel terminals (D1 to Dn) of said memory (101) so as to convert said parallel data of said memory (101) into serial data and input/output the serial data; a plurality of test terminals (311-1 to 311-n) connected to said parallel terminals (D1 to Dn) of said memory (101), respectively; and a switch control circuit (301) arranged between said parallel terminals (D1 to Dn) of said memory (101) and said parallel/serial conversion circuit (202), for disabling said parallel/serial conversion circuit (202). <IMAGE>
